Message from Dow to clear up any issues:
The process change that increased bromide levels in Dow calcium chloride products was implemented in December 2006. The first letter in the Dow lot number represents the year of manufacture. The letter "V" represents product manufactured in 2007, therefore any product with a lot number starting with "V" is product containing the higher levels of bromide impurity. Any lot number starting with a letter that precedes "V" in the alphabet, (such as "T" or "U"), would be product with the lower level of bromide impurity.
I hope this answers your question.
